How should I take GlipiZIDE XL?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Your dose may change if you switch to a different brand, strength, or form of this medicine. Avoid medication errors by using it exactly as directed on the label or as prescribed by your doctor.

Take GlipiZIDE XL 30 minutes before a meal.

Take the GlipiZIDE XL extended-release tablet once a day with breakfast or your first meal of the day.

Swallow the extended-release tablet whole and do not crush, break, chew, or dissolve it.

Your blood sugar will need to be checked regularly, and you may need other medical tests.

Part of the extended-release tablet shell may appear in your stool, but this will not make the medicine less effective.

Blood sugar can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals.

Low blood sugar (hypoglycemia) can make you feel very hungry, dizzy, irritable, or shaky. To quickly treat hypoglycemia, eat or drink hard candy, crackers, raisins, fruit juice, or non-diet soda. Your doctor may prescribe glucagon injection in case of severe hypoglycemia.

Tell your doctor if you have frequent symptoms of high blood sugar (hyperglycemia) such as increased thirst or urination. Ask your doctor before changing your medication dosage.

Your treatment may also include diet, exercise, weight control, and special medical care.

Store tightly closed at room temperature in the original container away from moisture and heat.
